I can tell you from my experience with him that I am very happy with the way the box sounds, can it be louder, sure for a very small frequency range but then everything else coming out of it would sound like a$$, the box he built for me hits hard for one 12, and it plays loud and clear no matter what music I play which is exactly what I wanted because I listen to new order, the cure, bushwick bill, metalica, candlebox, band of horses, black eyed peas, ice cube, tool, lynyrd skynyrd, lynkin park, I could go on, basically any type of music accept country, I like the old school country but the new stuff I feel is going away from real country music and trying to mesh with pop or top 40, blah blah..... anyways you will not be disappointed with your box.
also I am doing the same thing with him as far as building the box and waiting till black Friday to order the 2 HDC4 18's. it gives me time to do all the wireing, make the amp rack, find a location for the extra batteries ect.
